Simple Definition

Housing's "golden handcuffs": homeowners who locked in very low mortgage rates (many near 3% during the pandemic) are reluctant to sell, because moving means swapping that cheap loan for one at today's much higher rate. The result is frozen inventory and low sales volume.

Why It Matters

The lock-in effect is the main reason the housing market can "feel frozen" without a price crash: owners with cheap loans simply don't list, so supply dries up and transactions slow. The Mortgage Bankers Association estimated it kept over a million homes a year off the market. (Different from an IPO "lockup," which restricts insiders from selling new shares.)

Key Points

  • "Golden handcuffs" — a cheap old mortgage vs an expensive new one keeps owners from selling.
  • Freezes inventory and sales volume without necessarily crashing prices.
  • Eases as more owners come to hold rates near the current market rate.
